Improved Steady State and Transient Performance With Optimum Excitation of Single-Phase Self-Excited Induction Generator

This article deals with the performance prediction and analysis of the two winding single-phase self-excited induction generator (single-phase SEIG). A methodology of selection of capacitors for optimum excitation of the single-phase SEIG scheme is explained. Appropriate dynamic model of the system is developed incorporating the cross-saturation effect. This dynamic model is used for simulating realistic transients, such as no-load and on-load excitation, load perturbation, short-circuit condition, and re-excitation. Simulation results are confirmed by experimental investigation, thus providing verification of the derived model. The results are analyzed to obtain useful guidelines toward system improvements under such transients.
